no,no,no,no implication of any fault. Just trying to make the point that a
$20,000 work beater has multiple air bags and designed crumple zones,
but toter homes and rvs costing many times more

don't. I work for a domestic car manufacturer and our car was delayed coming to market by over a year because the crush zones and panels had to be reconfigured.
Should we not expect the same attention to safety in our tow rigs.
P.S. I use Michelins on our mh and change out the 2 oldest tires every year costs me a couple of bucks but is cheap compared to the cost of a blowout.
